This is a link to an Internet Archive 1912 publication entitled, Catalogue of All Catholic Books published in English.  This is an extensive list of works listed by author, subject, and title+author.  There is a total of 5,521 books listed.  Many of the books are re-publications of works written many years before this publication and many of these books are available on Internet Archive.  The problem has always has been in finding them.  With this reference you will be able to search for a specific book and/or author.  I have found it very helpful in finding great Catholic books that would have been otherwise very difficult to locate.
